Aliens are a new type of non-Human Sim available in The Sims 3 Seasons. These extraterrestrials visit the neighborhood to learn about Sims on Earth and may even abduct them and perform experiments. This guide will teach you how to get an Alien, Alien babies and Male Sim pregnancy, and the special abilities Aliens get in The Sims 3.

Finding Aliens

How to Get an Alien to Visit
Aliens have a chance to visit each night between 12am and 3am. A visit lasts only an hour and a half to two hours. Visits are distinct from abductions and allow your Sim to socialize, possibly befriend, and even ask an Alien to move in with them.

The base chance of a visit is 5%. Collect space rocks and store them on your lot. Once you've got five, aliens have a +15% additional chance to come to your lot. Once you've made friends with one, there will be an even greater chance of visits. If an Alien doesn't visit your home lot, there's a 20% chance each night they'll appear somewhere around the neighborhood and leave behind a few space rocks. When you've met an Alien, you can invite them over using the phone, so making friends with them is easy.

Alien visitors once befriended may be asked to move into your household. They always start with level 10 logic and level 7 handiness. This will give you permanent control over the Alien, along with their Galaxa Space Car.

Alien Abductions
Aliens are more likely to abduct a Sim than to visit, simply because of the powerful effect collecting space rocks has on this. To trigger an abduction on your home lot, having a Sim use a telescope is a good place to start. The base chance of an abduction is only 2%, but using a telescope that day adds a +13% chance they'll visit on a given night. Collecting up to two space rocks will each add a 37.5% chance to the visit for a whopping 90% chance of a visit. This seems to reset so that you don't always find your Sims getting abducted, giving you a little bit of control over how often it happens.

When a Sim is abducted, they'll have a bad Abducted moodlet for about twelve hours. Nothing too bad will happen to a female Sim, although a male has a 33% chance to have the pregnant (Unexpected Weight Gain) moodlet when the Abducted moodlet wears off. If you want to ensure your abduction results in pregnancy, save before this moodlet wears off and reload until the Unexpected Weight Gain moodlet appears.

Alien Babies and DNA

Male Pregnancy and Alien Babies
After a male Sim has been abducted and has later had the Unexpected Weight Gain moodlet appear, you know he is pregnant. The Sim will put on weight quickly as the baby grows, and birth will occur 48 hours later. You'll be asked if you want to keep the Alien Baby or send it back to its Homeworld. The choice is yours. If you keep the baby, you'll get to pick the traits. Raising an Alien baby is no different than a normal one.

Alien Pregnancy & Passing DNA
Of course, the Abduction pregnancy is not the only way to get a Sim with Alien powers in your household. Human Sims and Aliens can Woohoo and make babies. So long as the baby's DNA is at least 50% Alien, they will have access to alien telepathy powers and use the Brain Power motive instead of Energy. Supernaturals like Fairies and Werewolves can reproduce with Aliens, and may appear quite interesting (having mixed features of the parents), but the occult DNA will make the Alien powers unusable.

Alien Powers and Features

The Sims 3 Seasons' Alien Galaxa Space Car
An Alien Pilots a Galaxa Space Car

Alien Ship: The Galaxa Space Car
Aliens you invite to move in will come with their ship in their inventory. This is the fastest way to get around, as it can warp from one location to another in the blink of an eye. These can be upgraded with one of two upgrades, each requiring level 7 Handiness (which your Alien has). You can outfit them with laser cannons, which will let them use the craft to invade a lot of your choice. This is just for fun, and the user will indeed get a good moodlet out of it that is, while the targets on the ground have their clothing singed off.

The Other upgrade seems silly Space Travel. Can't it already do that given it's in your neighborhood? Oh well. Either way, outitting the spacecraft with this upgrade will allow the Sim to visit one of three places: The Moon, The Asteroid Belt, or The Planet Sixon to go on Rabbit-hole style text adventures which can reward valuable metals, gems, and a wide variety of items.

You can buy the Galaxa Space Car using the buydebug cheat.

Alien Brain Power
Aliens use Brain Power instead of the energy motive. They get to use Restore Brain Power (click the Alien) to restore this, much like meditation. They can fill their bar in 5 hours. They won't get a well rested moodlet, so popping into a bed for a few minutes can give them that mood boost. They'll also restore energy by consuming Space Rocks. The bigger the rock, the more power restored. The drawback to recovering their energy so quickly is that it's used to fuel their special abilities. They have one more major trick though, which can be used to help themselves or others:

Bio Boost and Bio Drain
Using Bio Drain on a Sim will sap his or her Social, Hygiene, and Fun motives and transfer them to the Alien over one hour. This refills about a third of each of these bars. The Alien could even use Restore Brain power or eat a meal after doing this to have four motives moving upward at once. The Alien may be giving, and use Bio Boost on a Sim to do the opposite and channel their needs to aid the target Sim in recovering theirs. Bio Boost and Drain can't be used on other Aliens.

An Alien transmutes a gem in The Sims 3 Seasons
An Alien Using the Transmute Brain Power

Transmute Object
Aliens can transmute Gems and Metals to make them higher value, or bump them up to the next most expensive item of that type. This is much more orderly than the Witch's transmutation. The odds of an item failing to transmute is determined by the value. An item under 100 Simoleons only has a 5% chance of failure, while any over 500 will fail 30% of the time. The mood of the Alien using this helps or hinders as well.

Forum member LordHellscream contributed a tip to making loads of cash with Seasons' Alien Transmute if you also have World Adventures installed. Learn how to use transfiguration to get filthy rich.

Repair Broken Objects
Aliens don't need the Handiness skill to repair broken household appliances and plumbing, they can do so with their minds. Quickly.

Scan and Probe Sims
Aliens can pull a joke on other Sims by whipping out the Probe, which will give them a scare before they hopefully laugh in relief. Their more useful ability is to Scan which consumes brain power but will teach you one of the target Sim's traits.

Summon Meteor
This requires The Sims 3 Ambitions Expansion Pack. Using a lot of Brain Power, an Alien can call down a meteor strike onto an area. This works just like the random meteors that may strike with Ambitions installed, only the Alien knows it's coming and can stand back and observe. This is a good source of Space Rocks for recovering Brain Power, and occasionally as a particularly catastrophic way to make money. People who don't have Ambitions can collect space rocks from the world and use the Steal Space Rocks option below.

Steal Space Rocks
Clicking the Science Lab between 8pm and 6am with an Alien Sim will allow them to go in and steal four Space Rocks. There's about a 60% chance they're tiny, 25% large, and 15% gigantic. This never seems to fail and is a neverending supply of cash for Aliens.

Sell Alien Secrets
At the Military Base in town, your Alien can sell what they know to betray their kind but profit nicely in the process. This can be done every 36 hours and will get you between 1500 and 2000 Simoleons. The interaction is available between 6am and 8pm.

Part-Time Career: Alien Test Subject
A new Part-time career exists only for Aliens. You can sign up at the Science Lab in town. There are three levels here, with mood being the only metric. All work M-F from 4-7PM. Associate Probe Testers make $64/hour, Specimen (Living) makes $84, and Organ Farms make $114 an hour. There's a 20% chance your Alien will be nauseous after work from all the strange experiments. Overall, stealing samples is more profitable than these jobs.

I also have the problem of not being abducted! I have numerous space rocks and add to the collection each day, I have full logic, and use the telescope! What am I doing wrong?

Ally says...
Try and put ALL the space rocks you have beside the telescope, between the hours of 12:00am and 3:00am and have your sim look through it. The first time I did it, it happened almost Immeadiatley but he didn't get pregnant. The second time I did it, it happened just as fast again and he did get pregnant.

Funny thing happened. I received the Weight Gain moodlet, went through all the days, birth happens, but with no baby. The baby didn't come, even though the game prompted me with the keep or return question and the naming part. Did this happen to someone else? The glitches and bugs in this update are driving me up the wall, primarily in my since-the-first-patch save in Sunset Valley, where this bug is irritating me.

Is your aging enabled? I remember way back if your aging wasn't enabled female sims couldn't give birth. It might be true for male abducties.

I have had two males abducted, one twice. Both of them were looking through the scope with rocks all around them. They heard a noise and ran to check it out. The aliens ships showed up on the other side of the house. The one taken twice the second time ended up pregnant.

Another male had a visitor, no matter how long or how many rocks I had, he was never abducted. They abducted his sister. He became friends with his visitor and they had a galactic long distance romance, she came to visit and they just married.

Oh my, and here I thought overseas long-distance relationships were the worst of them all.

I have the option on one sim called mind control with my alien. It forces the sim to clean my home. Though it so far appears on one npc sim.

Does anyone know how to add an alien to your household? My sim is level eight logic and every night searches the galaxy. I can't seem to find them around town. They abducted my sim once but never did he get pregnant. Someone please help! This is all i want to get done

Never mind, I got extremely lucky that I had a save prior the bug, so I reloaded, tried again, and now I have an Alien daughter who's in the Child phase. Whew.

I have an alien family, both mum and dad are aliens who were invited to move in by other sims before hooking up. But disappointingly their pure alien blood baby has human energy bars and needs and not alien ones. Anyone else have this problem with alien children?

the alien child wont have brain power bar til teen or young adult.

Sims don't have to be outside to get abducted, if they are inside the event will cause them to run outside. They can be doing something else, the action will just be interrupted by the abduction. There's no cooldown on the abductions, I had a sim abducted 3 nights in a row, but there also must be something more to the chance because that same sim also went over 2 weeks in a row without an abduction at one point while doing the same activities (collecting 2-3 space rocks per day and using the telescope at least once).

Visiting aliens mention skills when you greet them, and I wasn't visited a single time for over 6 weeks until my sim started maxing out skills, then they started coming multiple times per week. Could be coincidence.

Stealing space rocks from the science lab certainly does fail, and it results in your alien sim being arrested and spending the rest of the night in jail.

I saved my game with my guy having 2hours of time left on his abduction moodlet, and after 3-4 tries of reloading he got the unexpected weight gain moodlet. Then a few hours after getting abducted he got abducted again. lol
23rd November 2012 6:15pm
Willow says...
I had a female child show up out of now where shortly after being abducted like 3 times. My sim never got pregnant, just a child showed up lol so I am assuming that females just get a kid dropped off to them randomly from abductions.
24th November 2012 5:41am
Emma says...
My "abducted" moodlet only lasts 10 hours, and saving and relouding just before this moodlet ends never results in unexpected weight gain. Any ideas?
24th November 2012 12:28pm
Richard says...
Please can you help me, I have tried and tried to get an alien to vistbut nothing happens. I have 6 space rocks, my sim uses the telescope most nights and he has only been abducted once. Please can you help me, I really want to have an alien in my household but I can't find one anywhere! Please leave any suggestions :)

So for the jobs/town interactions, does the sim need to have 50%+ Alien DNA in order to do those, or can any sim with alien genetics also partake?
25th November 2012 2:24am
KelleyThatsMe says...
My female alien sim can't get pregnant. I have tried like ten times and still no baby. I don't understand.
25th November 2012 3:07am
Chuck says...
Hmmm, I had two alien abductions within three days using this guide, which was great. Unfortunately my Sim got stuck while having the abduction moodlet and had to be reset, and it's been over a week now still following this guide and abductions a no-go, I have gotten one visit though. Is there something that limits the abductions?
25th November 2012 1:14pm
Steven says...
Just a question can a occult sim get the unexpected weight gain moodlet and result in an alien baby? I have had a lot of trouble so far with my vampire sim and have gotten abducted but and done the save the load with the moodlet but it never results in pregnancy.
25th November 2012 5:11pm
Janna says...

You state that the time of visit is between 12 and 3 a.m. I started to check the time of my visits and forgot to note, they have all been after 3, the married man, his was almost 4 a.m. when he was abducted. So, those who may not be seeing aliens, try staying out after three.
26th November 2012 10:33pm
Alien Lover says...
try collecting space rocks from around town and put 5 of them on your property as well. This helps to increase the chance of an abduction and also a visit by aliens.
26th November 2012 11:16pm
Elizabeth says...
I saved when my sim only had 5 sim minutes left and then I saved it when he had only 3 sim minutes left. He got the Unexpected Weight Gain! xD

Brittany says...
I get Abducted every night, it's crazy too, went to a park late at night, and took one step onto the lot, and got abducted, haven't had any male pregnancies yet, due to the fact that I haven't made any male sims, but I do have a sim who is married to an alien and had an alien baby with them.

Do aliens ever walk around the 'hood randomly? I could swear I saw one at the Eerie Summer Festival in my game in Moonlight Falls. Either that, or a green-skinned sim (witch?).

My sims has been abducted numerous of times but I can't seem to call the aliens over the phone. Anyone know why?
